Map by Range TOP node

Map upstream work items to downstream work items using range values

On this page

Maps a range of upstream items to a range of downstream items. The range is determined by two main properties: the ratio of upstream work items to downstream work items, and an offset in the left and right direction.

For example, with Upstream Range set to 2 and Downstream Range set to 1, two upstream items will be mapped to each downstream item.

Parameters

Use Dynamic Mapping

By default, a mapper will establish dependencies between upstream static work items and downstream static work items. When this toggle is enabled, a second mapping pass will be done between any dynamic items above the mapper and static items below the mapper.

The dynamic items will be prefiltered based on the static mapping defined by the node, such that only dynamic items that descend from the selected static items will be considered.

Upstream Range

Along with the Downstream Range parameter, determines the ratio between upstream and downstream work items.

Downstream Range

Determines the number of downstream work items for each group of upstream work items specified in the Upstream Range parameter.

Left Offset

The number of additional items proceeding the selected items that should also be mapped to the downstream items.

Right Offset

The number of additional items that follow the selected items that should also be mapped to the downstream items.
